Question

A deli is trying out new labels for their cylindrical-shaped wheels of cheese. The label covers the entire wheel except the circular top and bottom.

If the wheel has a radius of 22 centimeters and a height of 16 centimeters, how many square centimeters of the wheel does the label cover?

Answer 1

704(pi) square centimeters.

To find the area of the sides of the cylinder, you must find the circumference first for the length.

C = 2(pi)r
C = 2(pi)22
C = 44(pi)

Area for the sides: A = C * h

44(pi) * 16 = 704(pi) square centimeters
